All names are always capitalized. That includes names of months, weekdays, geographical names (like for example cities). It also includes so-called "proper nouns" - terms that describe one specific entity - for example the Sun is the star at the center of our own solar system whereas a non-capitalized sun is just any other star. And finally it includes the names of languages and nationalities even when they are used as adjectives.
Alle Namen werden immer groß geschrieben. Das schließt die Namen von Monaten, Wochentagen, geografische namen (wie zum Beispiel Städte) ein. Es schließt auch sogenannte "proper nouns" - Begriffe die ein ganz spezielles Objekt bezeichnen - ein, zum Beispiel "the Sun" ist unsere Sonne, also der Stern im Zentrum unseres Sonnensystems, während eine nicht großgeschriebene "sun" einfach irgendein anderer Stern ist.

Words like "Freundeskreis" do not make sense literally (e.g. your friends don't form a circle around you or anything, do they?). You must never translate these words literally but rather look them up in the dictionary.
Wörter wie "Freundeskreis" ergeben keinen wörtlichen Sinn (z.B. deine Freunde formen nicht wirklich einen Kreis oder so um dich, oder?). Solche Wörter darfst du nicht wörtlich zu übersetzen versuchen sondern du solltest sie im Wörterbuch nachschlagen.

The usage of the definite article in English differs from the usage of our German definite articles. The rules are a bit too complex to be laid out here and now and, honestly, your best bet is to get a feeling for when an article is necessary by practise.
Die Verwendung des bestimmten Artikels im Englischen unterscheidet sich von der Benutzung der bestimmten Artikel im Deutschen. Die Regeln sind etwas zu umfangreich um sie hier auszuführen, und ehrlichgesagt, am besten ist es, wenn du durch Übung ein Gefühl dafür entwickelst, wann ein Artikel notwendig ist.
